- class EvaluationFactory(*p, **k)[source]
A Singleton class that provides Evaluation related objects.
Import from
taurus.core.evaluation
as:from taurus.core.evaluation import EvaluationFactory
- DEFAULT_AUTHORITY = '//localhost'
- DEFAULT_DATABASE = '_DefaultEvalDB'
- DEFAULT_DEVICE = '@DefaultEvaluator'
- elementTypesMap = {3: <class 'taurus.core.evaluation.evaldevice.EvaluationDevice'>, 13: <class 'taurus.core.evaluation.evalattribute.EvaluationAttribute'>, 18: <class 'taurus.core.evaluation.evalauthority.EvaluationAuthority'>}
- getAttribute(attr_name, **kwargs)[source]
Obtain the object corresponding to the given attribute name. If the corresponding attribute already exists, the existing instance is returned. Otherwise a new instance is stored and returned. The evaluator device associated to this attribute will also be created if necessary.
- Parameters:
attr_name (str) – the attribute name string. See
taurus.core.evaluation
for valid attribute names- Returns:
- Return type:
- Raises:
TaurusException if the given name is invalid.
Any aditional keyword arguments will be passed directly to the constructor of :class:EvaluationAttribute
- getAuthority(name=None)[source]
Obtain the EvaluationDatabase object.
- Parameters:
db_name (str) – this is ignored because only one database is supported
- Returns:
- Return type:
EvaluationDatabase
- getDevice(dev_name)[source]
Obtain the object corresponding to the given device name. If the corresponding device already exists, the existing instance is returned. Otherwise a new instance is stored and returned.
- Parameters:
dev_name (str) – the device name string. See
taurus.core.evaluation
for valid device names- Returns:
- Return type:
@throws TaurusException if the given name is invalid.
